Selenium offers a host of health benefits, as it is rich in antioxidants that fight free radicals, thereby protecting cells from damage. According to experts at the Helmholtz Center Dresden-Rossendorf in Germany, it contributes to the production and regulation of thyroid hormones and also strengthens the immune system. A selenium deficiency in the body can be identified by observing certain symptoms, such as a weakened immune system, thyroid problems, hair and nail issues, as well as persistent fatigue and exhaustion. Sources of selenium include animal foods such as fish, meat, eggs, and dairy products, as well as plant-based foods, particularly the Brazil nut, as just one nut is enough to cover the recommended daily amount, which ranges from 55 to 70 micrograms.
